<strong>JLR</strong>-<strong>10</strong> GPS Compass<br />
3. Installation<br />
3.1 Installation of the Antenna<br />
3.1.1 Choosing the Location<br />
CAUTION<br />
When connecting the cable attached to the equipment, do not bend it to an<br />
acute angle, twist it, or impart excessive force. Cracks or damage to the<br />
coating can cause a fire or electric shock.<br />
Do not install the antenna where there is excessive vibration.<br />
Accidents can be caused by receiving poor.<br />
Install the antenna where there is no viewing obstacle, in order to ensure that<br />
GPS signals can be directly received from satellites without interference or<br />
reflection of signals from surrounding objects.<br />
Whenever possible, select a place having the following characteristics.<br />
1. An open space which allows uniform reception of satellite signals.<br />
2. Far away from any high power transmission antennas.<br />
3. Outside of any radar beams.<br />
4. Away from the inmarsat antenna by at less 5 meters and below the level of its<br />
antenna.<br />
5. Away from the antenna of a direction finder, VHF or MF/HF by 5 meters or<br />
more.<br />
6. Away from a magnetic compass by at least 1 meter.<br />
If it is difficult to find an ideal site, select a place temporarily and install the antennas.<br />
Conduct a test to make sure that the proper performance can be obtained and then fix<br />
the antenna in position. If it is installed at an improper place, bearing accuracy is poorer,<br />
and accidents can be caused.<br />
